The pion single-event latch-up cross-section enhancement : mechanisms and consequences for accelerator hardness assurance

2021

Pions make up a large part of the hadronic environment typical of accelerator mixed-fields. Characterizing device cross-sections against pions is usually disregarded in favour of tests with protons, whose single-event latch-up cross-section is, nonetheless, experimentally found to be lower than that of pions for all energies below 250 MeV. While Monte-Carlo simulations are capable of reproducing such behavior, the reason of the observed pion cross-section enhancement can only be explained by a deeper analysis of the underlying mechanisms dominating proton-silicon and pion-silicon reactions. The mechanisms dominating the single-event latchup response are found to vary with the energy under c…

UAV-Assisted Data Collection in Wireless Sensor Networks: A Comprehensive Survey

2021

Wireless sensor networks (WSNs) are usually deployed to different areas of interest to sense phenomena, process sensed data, and take actions accordingly. The networks are integrated with many advanced technologies to be able to fulfill their tasks that is becoming more and more complicated. These networks tend to connect to multimedia networks and to process huge data over long distances. Due to the limited resources of static sensor nodes, WSNs need to cooperate with mobile robots such as unmanned ground vehicles (UGVs), or unmanned aerial vehicles (UAVs) in their developments. The mobile devices show their maneuverability, computational and energy-storage abilities to support WSNs in mul…

Socio-emotional Problems Experienced by Deaf and Hard of Hearing Students in Ethiopia

2015

This study compares the socio-emotional problems experienced by deaf and hard of hearing (DHH) students with those of hearing students in Ethiopia. The research involved a sample of 103 grade 4 students attending a special school for the deaf, a special class for the deaf and a regular school. Socio-emotional problems were measured using Goodman's self-report measure, the Strengths and Difficulties Questionnaire for children and adolescents. Participants were selected from seven towns in Ethiopia. The results show that, compared to the hearing sample, the DHH students experienced more severe socio-emotional problems across all dimensions, regardless of whether they were in special classes o…

Percorsi esistenziali del dialogo interreligioso. Scene vissute fuori campo

2016

Come pensare il dialogo tra le diverse religioni? Per rispondere a questa domanda, faccio appello a due frammenti di vita personale – l’incontro con due mormoni americani a Tartu e con un marocchino musulmano a Nîmes – per risalire all’origine del dialogo come forma di vita in divenire e alla forza del processo di consapevolizzazione che dovrebbe sussistere, nella mia ipotesi, in qualsiasi società per insegnare e apprendere a vedere l’alterità (religiosa) come un percorso di riposizionamento continuo del Sé e dell’altro. A questo fine, discuto alcune ipotesi formulate in antropologia delle religioni – più particolarmente da Evans-Pritchard per la religione nuer e da Geertz per la religione …

Synthesis, structural, and thermal characterization of a new binuclear copper(II) chelate complex bearing an amine-hardener for epoxy resins

2016

A new di(μ-carbonato)bis[aqua(diethylenetriamine)copper(II)] hexahydrate complex, [{Cu(NH(C2H4NH2)2)(H2O)(μ-CO3)}2]⋅6H2O (1), was synthesized by direct interaction of malachite with diethylenetriamine (dien). The crystals of 1 were characterized by X-ray powder diffraction and IR spectra, as well as structurally characterized. Compound 1 consists of [{Cu(dien)(H2O)(μ-CO3)}2] discrete units whose CO32– anions play the role of bridging ligands combining two Cu(II) chelate cores into a centrosymmetric dimer. The elongated octahedral environment of Cu2+ consists of three nitrogens of dien and an oxygen from CO32– at the base of the bipyramid; the two apical positions of such polyhedron are occu…

Recovery of aliphatic low-molecular-mass carboxylic acids from hardwood kraft black liquor

2015

Abstract During alkaline pulping of wood, substantial amounts of carbohydrates-derived aliphatic carboxylic acids (formic and acetic acids together with various hydroxy acids) are formed and dissolved into the cooking liquor (“black liquor”). These acids with low heating values are considered to be potential feedstocks for the chemical industry but, due to many factors, their straightforward recovery as free acids from black liquor (pH 13–14) is difficult. In this paper, we outlined the partial recovery of volatile formic and acetic acids from the acidified birch ( Betula pendula ) kraft black liquor (pH approximately 2.5) by distillation, and the partial recovery of significant low-molecul…

«Men for oss er det én Gud, Faderen» : et kritisk blikk på Richard Bauckhams kristologi

2012

Author's version of an article in the journal: Teologisk Tidsskrift. Also available from the publisher at: http://www.idunn.no/ts/tt/2012/01/art06 The article consists of two parts: Part one seeks to demonstrate (contra Bauckham) that Jewish monotheism in the Second Temple period was of a flexible character. It argues that Jewish writers in this period could attribute «divine functions» to figures beside God, while still feeling committed to «one God». The Jewish monotheism of this period was therefore not constituted by functions or characteristics, but rather by the exclusive worship of the one God. Part two argues that Paul describes Jesus with a high position beside God, while still fee…

Context-sensitive distraction warnings : effects on drivers' visual behavior and acceptance

2016

In this study, we investigated the effects of context-sensitive distraction warnings on drivers' in-car glance behaviors and acceptance. The studied prototype warning application functions on a smart phone. The novelty of the application is its proactive and context-sensitive approach to the adjustment of warning thresholds according to the estimated visual demands of the driving situation ahead. In our study, novice and experienced drivers conducted in-car tasks with a smart phone on a test track with and without the warnings. The application gave a warning if the driver's gaze was recognized to remain on the smart phone over a situation-specific threshold time, or if the driver was approa…
